LSM-9002LE

Fullauto StrainEye LSM-9002LE is a fully automatic 2D-measuring device which measures retardation values and the direction of a slow axis in a transparent body having strain and birefringence therein. In order to measure the direction and the birefringence, conventionally the visual observation type polariscope using the Senarmont method is used. The Senarmont method is an inspection method for measuring retardation quantitatively. An operator rotates the analyzer so that brightness of the part to be measured changes from the brightest state to darkest state, and measures its retardation by rotating the analyzer angularly.
